In this kinesthetic activity, learners act out the rotation and revolution motions of Earth around the Sun over the course of one year. Learners also physically model the tilt of the Earth and will identify the summer and winter solstice and vernal...(View More) and autumnal equinox locations in relation to Earth's orbit around the Sun.(View Less)

In this lesson, students compare different habitats based on satellite imagery and identify land features in the satellite image. This is lesson 3 in a unit on remote sensing that is a companion to an interactive adventure that uses a Landsat mosaic...(View More) of Arizona as the interface. Students need to interpret satellite imagery to receive clues to Echo the Bat's location. As students find Echo, additional content about remote sensing and biodiversity is introduced.(View Less)

In this paper and pencil exercise, students create graphs that describe the effect of a series of experiments using Daisy World, an energy balance model, that can be used to demonstrate concepts of equilibrium, homeostatis, and positive and negative...(View More) feedbacks. Internet access and exploration with the actual Daisy World model is ideal, but not required. The resource is Activity 6 of the learning module, Global Balance, part of the lesson series Potential Impacts of Climate Variability and Change.(View Less)

This is an activity about lunar and terrestrial stratigraphy. Learners will study the patterns of lava flow by creating eruptions using soda-vinegar solutions and modeling with home-made playdough (stove-top and no-cook recipes are included). This...(View More) activity is in Unit 2 of the Exploring the Moon teacher's guide and is designed for use especially, but not exclusively, with the Lunar Sample Disk program.(View Less)

Learners will research and document some of the requirements for mounting an expedition to an asteroid; actively explore potential resources available to space travelers through research, assessment, team cooperation, and exploration simulations;...(View More) develop the background to make the connection between meteorite research and potential planetary resources; and map and core an edible asteroid. Materials lists, and advanced preparation and procedural tips are included. This is lesson 17 of 19 in Exploring Meteorite Mysteries.(View Less)

This is a lesson about the effects of large impacts. Learners will use critical thinking skills to evaluate and apply data from a narrative to a scientific selection process, will demonstrate or visualize simulations of some of the effects of a huge...(View More) impact, and will write a point of view narrative. Materials and vocabulary lists, and advanced preparation and procedural tips are included. This is lesson 14 of 19 in Exploring Meteorite Mysteries.(View Less)
